However, currently Moscow and Washington are at odds over the Jaysh al-Islam militant groups. Russia has repeatedly urged to label it a terrorist group. However, the US has considered it a moderate armed group.
On May 17, the International Syria Support Group (ISSG) held a meeting in Vienna. The group issued a joint communique, having confirmed the previous agreements by the US and Russia. They include a joint transition governing institution in Syria by government and opposition representatives, a new constitution, and presidential and parliamentarian elections.
"Any effort by Russia and the international community is welcomed if it helps to restart talks between the sides in Geneva. It is good that the ISSG statement mentioned the importance of a timeframe for the political process, so it does not become endless and uncontrolled," the group said in a statement.
However, Saudi Arabia, a member of the ISSG, has rejected these provisions. Instead, Riyadh keeps insisting on the resignations of Syrian President Bashar Assad.
"We are moving toward the interruption of the Geneva peace talks," journalist Thierry Meyssan wrote in an article for Voltairenet.org.
On May 19, Qadri Jamil, one of the leaders of the Syrian Popular Front for Change and Liberation, said that Kurds could take part in one of the rounds of intra-Syrian talks in Geneva.
"They might [participate], though it is still unclear at what stage this may happen," Jamil told RIA Novosti.
"Instead, if Geneva talks end they should be replaced with resumed intra-Syrian negotiations, including those who wish to participate, including Kurds, but without Riyadh," he concluded.
